[0007] Problems to be solved by the invention

[0008] In the past, depending on the size and shape of the seedling, it was necessary to make a seedling raising basin of different sizes and shapes. Therefore, there was a shortcoming that the manufacturing cost of the seedling raising basin was high and the management thereof was troublesome.

[0009] In particular, it is difficult to change the shape of the opening end of the seedling raising pot.

[0010] Therefore, an object of the present invention is to provide a seedling raising pot that solves the above-mentioned disadvantages.

[0011] Means for solving problems

[0012] The first invention for solving the above-mentioned problems is a seedling raising basin, which is formed with a basin body 4, the basin body 4 having: a peripheral surface portion 1 formed in a polygonal cylindrical shape in a plane, a bottom 2 closing the lower end side of the peripheral surface portion 1, and an open end portion 3 opened at the upper end side of the peripheral surface portion 1, and each side 6 of the polygon around the opening end portion 3 is formed with a folded portion 10, wherein:

[0013] The folded portion 10 is fixed in a state of being folded back from the upper edge 9 of the opening end portion 3 toward the inner side or the outer side of the peripheral surface portion 1 and toward the bottom portion 2.

[0014] The front end of the folded portion 10 becomes a free end 10a.

[0015] The folded portion 10 is formed with one or more slits 14 or cut lines 15 extending from the free end 10a toward the upper edge 9.

[0016] The middle position of the side 6 of the opening end 3 is formed so as to be able to bend in the direction opposite to the center O of the opening end 3 at the position of the slit 14 or the cutting line 15.

[0017] In a state where the middle position of the side 6 of the opening end portion 3 is bent, an additional top portion 5 a added to the polygonal top portion 5 of the opening end portion 3 is formed at the bent position.

[0018] The second invention for solving the above-mentioned problem is a seedling raising basin, which is formed with a basin body 4, the basin body 4 having: a peripheral surface portion 1 formed in a polygonal cylindrical shape in a plane, a bottom 2 closing the lower end side of the peripheral surface portion 1, and an open end portion 3 opened at the upper end side of the peripheral surface portion 1, and each side 6 of the polygon around the opening end portion 3 is formed with a folded portion 10, wherein:

[0019] The folded portion 10 is fixed in a state of being folded back from the upper edge 9 of the opening end portion 3 toward the inner side of the peripheral surface portion 1 and toward the bottom portion 2.

[0020] A tongue portion 12 is formed at the end portion 11 of the folded portion 10, and the front end of the tongue portion 12 becomes a free end 13.

[0021] The tongue portion 12 is formed with one or more slits 14 or cut lines 15 extending from the free end 13 toward the end 11 of the folded portion 10.

[0022] The middle position of the side 6 of the opening end 3 is formed so as to be able to bend in the direction opposite to the center O of the opening end 3 at the position of the root of the slit 14 or the cutting line 15 and the end 11.

[0023] In a state where the middle position of the side 6 of the opening end portion 3 is bent, an additional top portion 5 a added to the polygonal top portion 5 of the opening end portion 3 is formed at the bent position.

[0024] A third invention for solving the above-mentioned problem is a seedling raising pot according to the second invention, wherein the tongue piece 12 is divided by the slit 14, and a divided tongue piece 12a is provided.

[0025] In a state where the middle positions of the sides 6 of the opening end portion 3 are bent, the front ends of the divided tongue pieces 12a extend toward the center O of the opening end portion 3, and parts of the divided tongue pieces 12a overlap and cross each other.

[0026] A fourth invention for solving the above-mentioned problems is the seedling raising pot according to the first invention or the second invention, wherein a length L3 of the folded portion 10 is substantially equal to a length L4 of the side 6 of the polygon.

[0027] A fifth invention for solving the above-mentioned problems is a seedling raising pot according to any one of the first invention and the second invention, wherein the length from the center O of the pot body 4 to the middle position of the polygonal side 6 at the opening end 3 to the periphery of the opening end 3 is set to L1.

[0028] The basin body 4 can take a first state and a second state.

[0029] The first state is a state in which the length L1 is not expanded.

[0030] The second state is a state in which the length L1 is expanded by bending the side 6 of the opening end 3, and an additional top 5a is formed at the middle position of the side 6 of the first state in addition to the top 5 of the polygon in the first state.

[0031] In the first state, the intermediate position has one or more variable portions 7 that can expand the length L1 and become the additional top portion 5a in the second state.

[0032] The slit 14 or the cut line 15 can be changed from the first state to the second state in which the additional top portion 5 a is formed, in a state in which the length L1 is expanded while being cut off to the variable portion 7 in the first state.

[0033] Effects of the Invention

[0034] The first invention is a seedling-raising basin, in which one or more slits 14 or cutting lines 15 extending from the free end 10a thereof to the upper edge 9 are formed at the folded portion 10, and the middle position of the side 6 of the opening end 3 of the basin body is formed to be able to bend in the direction opposite to the center O of the opening end 3 at the position of the slit 14 or the cutting line 15, and in a state where the middle position of the side 6 of the opening end 3 is bent, an additional top 5a is formed at the bent position in addition to the polygonal top 5 of the opening end 3.

[0035] According to this structure, the shape of the opening end 3 of the pot body 4 can be changed according to the position of the slit 14 or the cut line 15. Therefore, a certain size of seedlings can be handled with one type of seedling raising pot, and the manufacturing cost can be reduced. At the same time, since the types of molds for seedling raising pots to be manufactured are reduced, their management becomes easy.

[0036] The second invention is a seedling-raising basin, in which one or more slits 14 or cutting lines 15 are formed on the tongue portion 12, extending from its free end 13 to the end 11 of the folded portion 10, and the middle position of the side 6 of the opening end 3 is formed to be able to bend in the direction opposite to the center O of the opening end 3 at the root position of the slit 14 or cutting line 15 and the end 11, and when the middle position of the side 6 of the opening end 3 is bent, an additional top 5a is formed at the bent position in addition to the polygonal top 5 of the opening end 3.

[0037] Even in the above-described configuration, similarly to the first invention, the shape of the opening end portion 3 of the bowl body 4 can be changed by the position of the slit 14 or the cut line 15 .

[0038] The third invention is a seedling-raising basin, which, on the basis of the seedling-raising basin described in the second invention, includes a split tongue portion 12a formed by splitting the tongue portion 12 formed by a slit 14, and in a state where the tongue portion 12 is bent at the middle position of each side 6 of the opening end portion 3, the front end of each split tongue portion 12a extends toward the center O side of the opening end portion 3, and a portion of each split tongue portion 12a crosses and overlaps.

[0039] According to this structure, compared with the case where the undivided tongue pieces 12 overlap crosswise, the floating of the overlapping parts is reduced, and the rolling up of the divided tongue pieces 12a covering the upper part of the culture soil can be prevented, thereby improving the weed control effect of the divided tongue pieces 12a.

[0040] In the fourth invention, the length L3 of the folded portion 10 is substantially identical to the length L4 of the side 6 of the polygon.

[0041] According to this configuration, the entire length L3 of the folded portion 10 in the extending direction of the side 6 substantially matches the length L4 of the polygonal side 6 , thereby being able to sufficiently maintain the shape of the open end portion 3 before the middle portion of the side is bent.

[0042] Furthermore, even with a configuration like the fifth invention, the effects of the first invention or the second invention can be obtained. BRIEF DESCRIPTION OF THE DRAWINGS

[0050] The pot body 4 of the seedling raising pot of the present invention includes a peripheral surface 1 formed in a polygonal cylindrical shape in plan view, a bottom 2 closing the lower end side of the peripheral surface 1, and an opening end 3 opened at the upper end side of the peripheral surface 1.

[0051] The peripheral surface portion 1, the bottom portion 2, and the opening end portion 3 are integrally formed of the same material.

[0052] The material of the seedling raising pot is preferably flexible. As an example, a nonwoven fabric having light-shielding properties can be used.

[0053] Any material that is easy to process, such as paper, can be used as a substitute.

[0054] Next, embodiments of the present invention will be described based on the drawings.

[0055] Example 1

[0056] Figure 1A , Figure 1B as well as Figure 3A to Figure 3C This figure shows the shape of the first state of the first embodiment. Figure 2A to Figure 2C The expanded state and the manufacturing process of this embodiment are shown.

[0057] like Figure 1AAs shown, the seedling raising pot has a peripheral surface portion 1 formed in a square cylindrical shape in a plan view, and the lower end side of the peripheral surface portion 1 is closed by a bottom portion 2. The upper end side of the peripheral surface portion 1 is an open end portion 3 that is opened.

[0058] A folded portion 10 is formed on each side 6 of the polygonal shape at the peripheral edge of the opening end portion 3. The folded portion 10 is fixed in a state of being folded from the upper edge 9 of the opening end portion 3 toward the inner side of the peripheral surface portion 1 and toward the bottom portion 2 side.

[0059] A tongue portion 12 is formed at the end portion 11 of the folded portion 10. The front end of the tongue portion 12 is a free end 13. A slit 14 is formed in the tongue portion 12, extending from the free end 13 of the tongue portion 12 to the end portion 11 of the folded portion 10. As shown in each of FIGS. 1 to 3 , the slit 14 of this embodiment is formed from the free end 13 of the tongue portion 12 to the end portion 11 of the folded portion 10.

[0060] The middle position of the side 6 of the opening end 3 is formed to be bendable in the direction opposite to the center O of the opening end 3 at the base of the slit 14 and the end 11. The variable portion 7 serving as the additional top 5a is provided at the bendable position.

[0061] In other words, when the length from the center O of the basin body 4 at the opening end 3 to the middle position of the polygonal side 6 of the periphery of the opening end 3 is set to L1 (hereinafter referred to as the length L1), the basin body 4 can take a first state in which the length L1 is not expanded as shown in the figures of Figure 3 and a second state in which an additional top 5a is formed at the middle position of the side 6 in the first state in which the length L1 is expanded in addition to the top 5 of the polygon in the first state as shown in the figures of Figure 4.

[0062] A variable portion 7 that can be expanded by a length L1 and that becomes an additional top portion 5a in the second state is provided at a middle position of a side 6 of the opening end portion 3 .

[0063] In the first state, if Figure 3A As shown, the length L1 is not expanded and is shorter than the length L2 (hereinafter referred to as the length L2 ) of the top 5 of the polygon from the center O of the bowl body 4 to the periphery of the opening end 3 at the opening end 3 .

[0064] The seedling pot of this embodiment is as follows Figure 2A As shown in the development view of FIG. 1 , the bottom 2, the peripheral surface 1, the folded portion 10 and the tongue portion 12 of the seedling raising pot are integrally formed by a single mold. Figure 2B , Figure 2C The order of formation.

[0065] like Figure 2B As shown, each folded portion 10 is folded toward the bottom 2 side at the inner side of the peripheral surface portion 1 and joined to the inner surface of the peripheral surface portion 1 .

[0066] Then, if Figure 2C As shown, the front end of the tongue piece 12 is folded from the position of the end 11 of the folded portion 10 toward the upper side of the bowl body 4. Each tongue piece 12 is temporarily fixed to each folded portion 10.

[0067] like Figure 2A As shown in the development view of , the length L3 of the folded portion 10 (hereinafter referred to as length L3) and the length L4 of the polygonal side 6 of the opening end portion 3 (hereinafter referred to as length L4) are preferably formed so that the length L3 is slightly shorter than the length L4.

[0068] The width L5 of the longest portion of the tongue piece 12 formed at the end 11 of the folded portion 10 is preferably the same as the length L3.

[0069] In this embodiment, if Figure 1A , Figure 2A As described above, the tongue portion 12 is formed semicircularly from the end portion 11 of the folded portion 10, and the front end of the tongue portion 12 is a notch portion 16. However, the shape of the tongue portion 12 is not limited to this.

[0070] When the basin body 4 is used in the unbent state (first state), Figure 1B As shown, each tongue piece 12 temporarily fixed is pulled back so as to cover the surface of the culture soil 18, and a part of the adjacent tongue piece 12 is crossed and overlapped in sequence to form a cover covering the culture soil 18.

[0071] Figure 4A to Figure 4C The second state of the seedling raising pot of the first embodiment (a state in which the middle position of the side 6 of the opening end portion 3 is bent) is shown.

[0072] In the second state, an additional top 5a is formed at the curved position in addition to the polygonal top 5 of the opening end 3. In other words, the length L1 is extended, and the additional top 5a is formed at the position of the variable portion 7 in the first state.

[0073] The folded portion 10 is bent at the position of the additional top portion 5 a of the opening end portion 3 , and the other portions maintain the shape of the opening end portion 3 in the second state.

[0074] In the second state of this embodiment, the tongue portion 12 is divided into divided tongue portions 12a by the slit 14. Parts of each divided tongue portion 12a overlap and cross each other to form Figure 4A status.

[0075] When the divided tongue pieces 12a overlap crosswise, the floating of the overlapping part is reduced compared to the case where the undivided tongue pieces 12 overlap crosswise, and the rolling of the divided tongue pieces 12a covering the upper part of the culture soil can be prevented, and the weed prevention effect of the divided tongue pieces 12a is improved. In addition, the aesthetics of the overlapping state of the divided tongue pieces 12a is improved compared to the case where there is no floating of the tongue pieces 12.

[0076] In the second state of this embodiment, the planar shape of the opening end portion 3 is an octagon, and the planar shape of the bottom portion 2 is a square.

[0077] In the second state, if Figure 4B As shown, by forming the additional top portion 5 a , a peripheral surface expansion portion 1 a reflecting the shape of the additional top portion 5 a is formed on the peripheral surface portion 1 of the bowl body 4 .

[0078] Example 2

[0079] FIG5 shows a second embodiment of the present invention.

[0080] In the second embodiment, the slit 14 is formed from the free end 13 of the tongue piece 12 in the first state to just before the end 11 of the folded portion 10 .

[0081] When changing from the first state to the second state, the slit 14 formed from the free end 13 of the tongue portion 12 in the first state to the front of the end 11 of the folded portion 10 is set to a state in which the incision is extended to the position of the variable portion 7 at the end 11 of the folded portion 10 using scissors or the like.

[0082] As a result, the additional top portion 5 a in the second state is formed at the position of the variable portion 7 .

[0083] In addition, the difference from the first embodiment is that in the first state, the opening end 3 of the basin body 4 is triangular in plan view, and in the second state, the opening end 3 is hexagonal in plan view. In addition, in the first state of this embodiment, there are three tongue pieces 12, and in the second state, six divided tongue pieces 12a are formed by the extended slits 14.

[0084] Thus, the present invention is also applicable even if the shape of the opening end portion 3 of the bowl body 4 when viewed in a plan view is a polygon other than a quadrilateral.

[0085] Example 3

[0086] 6 and 7 show a third embodiment of the present invention.

[0087] The third embodiment is different from the first embodiment in that the tongue piece portion 12 is removed.

[0088] In this embodiment, a folded portion 10 is formed as the rigid portion 8 from the upper edge 9 of the opening end portion 3 toward the inside of the peripheral surface portion 1 and toward the bottom portion 2 , and the front end of the folded portion 10 is a free end 10 a .

[0089] In this embodiment, a cut line (cut mark) 15 such as a perforated line is formed instead of the slit 14 of the first and second embodiments. The cut line 15 is formed from the free end 10 a of the folded portion 10 toward the upper edge 9 .

[0090] Furthermore, a variable portion 7 is provided at the position of the cut line 15 in the middle of the side 6 of the opening end portion 3 so as to be bend in the direction opposite to the center O side of the opening end portion 3 .

[0091] The cut line 15 is easier to maintain the rigidity of the variable portion 7 and the shape of the first state of the opening end portion 3 than the slit 14. When changing from the first state to the second state, the cut line 15 is set to a state of being cut from the free end 10a to the upper edge 9.

[0092] Thus, even if there is no tongue portion 12, Figure 7B As shown, the shape of the opening end portion 3 can also be changed from the first state to the second state.

[0093] In addition, the opening end portion 3 in the second state is bent at the position where the top portion 5 a is added, and the other portions maintain the shape of the opening end portion 3 in the second state due to the rigidity of the folded portion 10 .

[0094] The folded portion 10 may be folded back from the upper edge 9 of the opening end portion 3 toward the outside of the peripheral portion 1 and toward the bottom 2. This structure makes it easier to perform cutting when cutting along the cutting line 15 when the second state is reached, compared with a structure in which the folded portion 10 is folded back toward the inside of the basin body 4.

[0095] (Other embodiments)

[0096] The notch portion 16 in the first embodiment and the second embodiment may be formed as required.

[0097] The slits 14 in the first and second embodiments may be cut lines 15 such as perforated lines in the third embodiment.

[0098] In each embodiment, the peripheral surface portion 1 of the bowl body 4 expands from the bottom portion 2 toward the opening end portion 3. However, the peripheral surface portion 1 does not need to be inclined in the first state.

[0099] In the first or second embodiment, one slit 14 is formed at the center of the width direction of each tongue piece 12. In the third embodiment, one cut line 15 is formed at the center of the width direction of each folded portion 10.

[0100] The present invention is not limited thereto, and one or more slits 14 or cut lines 15 may be formed. In this case, the slits 14 or cut lines 15 are formed to be separated from each other.

[0101] The second state of the present embodiment is preferably a state in which the additional top 5a is formed on each side 6. The present invention is not limited to this, and the additional top 5a may be formed on one or more sides 6.

[0102] Industrial Applicability

[0103] The present invention can be used as a seedling raising pot for raising seedlings of flowers, fruit trees, etc.
